LeetCode 3405 | Hard | Combinatorics You are given three integers: n: length of the array m: range of values [1, m] k: number of adjacent equal pairs You must find the total number of "good arrays", where: Every element lies in the range [1, m] Exactly k indices i (where 1 ≤ i < n) satisfy arr[i - 1] == arr[i] Since the result may be large, return the count modulo 10⁹ + 7. To construct a valid array: Pick k positions (from the n - 1 possible adjacent pairs) to be equal. The first element can be any value from 1 to m. For each of the n - 1 - k remaining positions (which must differ from the previous element), there are m - 1 options. So, the total number of such arrays is: C(n - 1, k) × m × (m - 1)^(n - 1 - k) Where: C(n - 1, k) is the number of ways to choose k adjacent positions to…  ( 5 min )

This section demonstrates the features and usage of the new Indicator navigation point component in HarmonyOS API 15. DevEco Studio 5.0.5 Release The Indicator navigation point component offers two styles of navigation points: dot navigation points and digit navigation points. This component has been supported since API Version 15. It provides the existing capabilities of the Indicator in the original Swiper component as a standalone component for developers to use. Developers can display navigation points independently without relying on the Swiper component, or they can bind it with the Swiper component using the IndicatorComponentController. When multiple navigation point components are bound to the same Swiper component, only the last navigation point component will successfully bind t…  ( 6 min )

Presented at DevFest 2024, Johannesburg Artificial Intelligence is no longer the exclusive domain of massive corporations or high-end research labs. With the rise of open-source models like Gemma and modular frameworks like LangChain, it is now possible to build robust, domain-specific AI systems using publicly available tools. At DevFest Johannesburg 2024, I walked through how to build a Retrieval-Augmented Generation (RAG) system using Gemma, LangChain, and Vertex AI — with a working chatbot demo and live deployment. RAG is an AI architecture that combines: Information retrieval (search, databases, document indexes) Generative language models (like Gemma or Gemini) This enables systems to access external knowledge, retrieve relevant content, and use that content to ground the generation …  ( 5 min )

What is a Hook? Hooks allow function components to have access to state and other React features. Because of this, class components are generally no longer needed. Hooks allow us to "hook" into React features such as state and lifecycle methods. Why used Hooks? Although Hooks generally replace class components, there are no plans to remove classes from React. Hook Rules** There are 3 rules for hooks: Hooks can only be called inside React function components. Note: Hooks will not work in React class components. useState in React React's useState hook lets you add state to functional components. import { useState } from 'react'; function Counter() { return ( Count: {count} An array is a list-like object used to store multiple values in a single variable. const fruits = ['apple', 'banana', 'cherry']; Arrays can hold any data type — strings, numbers, objects, or even other arrays. The Spread Operator (...) The spread operator allows you to quickly copy or merge arrays and objects. const original = [1, 2, 3]; console.log(copy); // [1, 2, 3] Adding elements: const numbers = [1, 2, 3]; console.log(moreNumbers); // [1, 2, 3, 4, 5] Merging arrays: const a = [1, 2]; console.log(combined); // [1, 2, 3, 4] Using map() to Transform Arrays The map() method lets you apply a function to every element in an array and returns a new array. const numbers = [1, 2, 3]; console.log(doubled); // [2, 4, 6] In React, map() is commonly used to render lists of components: const items = ['pen', 'notebook', 'eraser']; return ( {item} )} );  ( 3 min )

"Your database is fighting itself—and the reads are winning."

What is Blockchain? Blockchain is a decentralized, permanent digital ledger that records transactions across many computers. This setup makes it nearly impossible to change past records. Instead of relying on a central authority (like a bank), blockchain promotes transparency, security, and efficiency by sharing control among participants. Transactions are grouped into blocks, and each block links to the previous one, creating a chain. These blocks are protected using cryptography, ensuring the data inside can’t be altered once added. A blockchain runs on a peer-to-peer network. When a transaction happens: It is broadcast to many computers (called nodes). The nodes verify the transaction through consensus methods like Proof of Work (PoW) or Proof of Stake (PoS). Verified transactions are…  ( 5 min )

As a student developer who is exploring AWS technologies, I recently came across Amazon Q and its current event. The event encouraged participants to build a game, and that instantly hit a nostalgic chord in me. A few years ago, I've created a simple game in Unity without knowing how to code. Now, equipped with two years of coding experience and the help of Amazon Q, I managed to recreate that idea as a full parody arcade game using pygame-ce in just one day! Although AI tools are not new to me and to everybody, it still amazes me how much faster development becomes with the use of it. So in this short post, I’ll be sharing a quick look at how Amazon Q helped me bring this fun small project to life. The game is called the "The Last Bluebook".

This is the third release of Pulumi Gestalt, a universal runtime for Pulumi. Pulumi schemas have traditionally been stored in YAML files, but the complexity of their content often leads to a lot of boilerplate when mapping into domain objects. In Pulumi Gestalt 0.0.3, both the Rust and C FFI targets (Wasm coming later) now support obtaining schemas as native Rust structs or serialized Protobuf messages for C. The Protobuf schema is designed to be straightforward—no additional mapping logic required.

TL;DR: When building a real-time video rendering and encoding pipeline in C++, I hit a surprising bottleneck: memory allocation. Despite using high-performance libraries like OpenGL and FFmpeg, the cost of safely copying ~5MB per frame killed my frame budget. The fix? Using raw pointers with a manually managed double buffer. It’s not idiomatic C++, but in this case, “unsafe” code—done carefully—was the only way to hit performance targets. As a person who worked in managed runtimes like NodeJs and the Golang runtime, thinking about memory management always felt like premature optimisations because the runtime, or the underlying libraries generally handled it really well. However, in C++ it is the name of the game. The language offers multiple ways to manage memory and resource lifecycles …  ( 5 min )

A groundbreaking study from Japan has uncovered direct brainwave patterns linked to our experience of happiness. Using advanced magnetoencephalography, or MEG, scientists identified a clear neural signature that differentiates happier minds from the rest. Researchers recorded brain activity from volunteers at rest and compared those signals against their self reported happiness levels using standard psychological questionnaires. They discovered that higher subjective happiness was associated with lower fluctuations in gamma band electrical activity in a key brain region called the right precuneus. This area is known to be involved in self awareness and mind wandering. To reach this conclusion, the team employed a 400 channel MEG helmet to capture high resolution brain data.

Today hit us with another round of Apple rejection. 😅 This time it wasn’t technical — at least not completely. Apple flagged us for a broken link and asked for further clarification on what our app actually does. It’s frustrating, sure. After working so hard to build something safe, educational, and magical for kids — it’s a gut punch to feel like we’re stuck behind bureaucracy. But we're not giving up. We took today to carefully review the rejection notes, update our metadata, fix the link issue, and prepare a new submission. The worry now is time: with only 13 days left, will we have a working version live in the store before the hackathon ends? It’s a risk, but we’re still in this. We believe in Story Hero too much to let some red tape stop us. The Apple review process is famously opaque. But we’re committed to learning it, navigating it, and getting this app live — even if it takes a few more tries. One way or another, we’ll launch.

Open your favorite banking app. Tap to send money. If it hesitates even a second, what do you do? That brief pause – barely noticeable in most apps – can be a deal-breaker in financial services. Trust is measured in milliseconds. According to a study by Akamai, a mere 100-millisecond delay in website load time can hurt conversion rates by 7%. For mobile banking, where stakes are higher and users are less forgiving, the impact compounds. FinTech isn’t just software – it’s infrastructure. And users expect infrastructure to be fast, always available, and invisible when working correctly. When it fails, it’s not just annoying – it’s a breach of trust. Performance QA testing for mobile apps in banking and payments is no longer a nice-to-have. It’s a safeguard for customer retention, brand credi…  ( 7 min )

"A confusão começa quando diferentes áreas de negócio compartilham um mesmo modelo de dados." — Eric Evans Com o crescimento de aplicações, principalmente em arquiteturas de microserviços, cresce também a complexidade de lidar com múltiplos domínios de negócio. É aí que entra o DDD (Domain-Driven Design) e seu conceito-chave: o Bounded Context. Neste artigo, vamos explorar como aplicar DDD com Bounded Contexts na prática, utilizando .NET 8, organização de pastas e exemplos reais. Um Bounded Context é uma fronteira explícita dentro de um domínio, onde um modelo específico é definido e aplicado de forma consistente. Na prática, isso significa separar funcionalidades como Financeiro, Cadastro, Logística, etc., em contextos independentes — cada um com seu vocabulário, regras de negócio e estru…  ( 5 min )

The most impressive addition is automatic comment generation. An on-device model analyzes your code and writes contextual comments that translators actually need. We've all been there. You write a string like this: Text("Delete", comment: "Delete button shown in an alert asking for confirmation to delete the collection.") But more often, we rush and write this: Text("Delete") // TODO: Add comment for translators The TODO never gets done. Translators see "Delete" with zero context. Is it a verb? A noun? What's being deleted? Right-click any string in your String Catalog and select "Generate Comment." The results are surprisingly sophisticated: // Original string with no context Button("Cancel") { } // AI-generated comment: // "The text label on a button to cancel the deletion of a collec…  ( 6 min )

Amazon/AWS people speak a lot on how they're customer obsessed, and have a bias for action. And sometimes it sounds like talking points. But, lately, I got to experience first-hand how AWS listens (and reacts) to community feedback! The story is actually quite short, given how fast my feedback was taken into account. On May 19th, I created an IAM user for a subcontractor, let's call him John, who was supposed to work on a data lake project, so I named that user john and put him in the /datalake/ path. I set a temporary Console password and assigned the IAMUserChangePassword policy to that user. But later that day, John gets in touch; quite pissed: "I can't reset the password for the account you gave me, and as a result AWS won't let me sign in". At first, I couldn't understand: I had d…  ( 4 min )

1. Introduction Solidity is one of the most widely used programming languages in the Web3 space, especially on Ethereum and Ethereum Virtual Machine (EVM) compatible chains. As smart contract development has evolved, developers have encountered several challenges, particularly when trying to build complex, upgradeable, and gas-efficient contracts. One major limitation is Solidity's 24KB maximum contract size, which restricts the amount of logic that can be deployed in a single contract. This has led developers to explore different upgradeability patterns and modular architectures. To address these limitations, Nick Mudge proposed the Diamond Standard (EIP-2535). This standard provides a framework for building modular, upgradeable smart contracts in a structured way. By organizing contrac…  ( 6 min )

One thing I learned about: Alternatives to using blockchain nodes Blockchains do not always need to use full nodes for every task in the network. They can use alternatives suited to their goals, circumstances, and constraints. Examples: Light clients: performs trust-minimized verification by requesting proofs from full nodes. Data availability layers: store and serve block data apart from execution nodes. Layer2 and sidechains: process data off-chain and rely on proofs or state roots. Blockchain indexers: store data and allow queries nodes do not support. Remote or federated APIs: third-party on-chain data providers 🔽🛠️Resources🔽 What is Data Availability in Blockchain?

“Rust is the skill. Polkadot is the playground. And you? You’re the architect.” For the past few months, I’ve been heads-down writing about Go — breaking down structs, interfaces, and everything in between. It was the language that helped me fall in love with code and gave me a strong foundation in backend development. But something kept calling me: blockchain. As I explored the space, I didn’t want to just write smart contracts or build on top of existing blockchains. I wanted to understand the core — the real infrastructure that powers the decentralized world. That’s when I stumbled into the Polkadot ecosystem — a vision of Web3 that goes beyond just blockchains. It’s about connecting them all, and empowering developers to build their own chains using powerful tools. And guess what? The …  ( 5 min )

Every developer using an AI coding assistant has felt the jarring whiplash of its brilliance and its absurdity. One moment, it scaffolds a complex class structure perfectly; the next, it confidently uses a deprecated method or hallucinates an API that never existed. This problem becomes critical when building complex, stateful systems like those powered by LangGraph. An unguided AI can quickly lead you down a rabbit hole of debugging non-existent features. But what if, instead of just prompting and hoping for the best, we could engineer the environment our AI assistant operates in? What if we could force it to be a reliable, expert partner? This article introduces a framework to do just that. It's a system for grounding AI assistants, making them highly effective tools for building product…  ( 6 min )

Picture this: You've containerized your full-stack application, everything works beautifully in development, but when you deploy to production, services can't find each other, performance tanks, or worse - security boundaries disappear. Sound familiar? Docker networking is often treated as a "set it and forget it" configuration, but understanding the three core networking modes - Bridge, Host, and Overlay - can be the difference between a scalable, maintainable application and a debugging nightmare. In this guide, we'll explore each networking mode through the lens of a practical e-commerce application, examining when to use each approach and the trade-offs involved. Before diving into specific network types, let's establish our example application architecture: E-Commerce Stack: ├── Front…  ( 8 min )

So you've decided to build a complex, multi-step AI agent. You fire up your AI coding assistant, describe your goal, and ask it to scaffold a LangGraph application. What you get back looks plausible, but then you spot it: a call to a deprecated function, an import from a library that's changed, or a hallucinated parameter that doesn't exist. This is the chaotic reality of modern AI-driven development. Our tools are incredibly powerful but operate with outdated knowledge and no sense of best practices. It feels like working with a brilliant but forgetful intern. What if we could change that? What if we could build a system that forces our AI assistant to be a reliable, expert partner?

Ever wondered if you should use Transfer Learning or go all-in with Fine-Tuning when adapting a pretrained model? 🤔 If you’re working with something like BERT or LLaMA 2, choosing the right approach can save you serious time and compute costs. Here’s the quick breakdown: Transfer Learning is great when you just need to tweak the model a bit freeze most layers, retrain the final ones, and you’re good to go. Fast and efficient. Fine-Tuning, on the other hand, updates the whole model. It’s heavier, but sometimes necessary when your use case is highly domain-specific (think legal, medical, or financial AI). We made a short video explainer that walks through both options and when to use each. If you’re building anything from sentiment classifiers to custom chatbots, it might help clarify the path forward. Let us know if you're exploring this in your own AI project! 👀  ( 3 min )

Hot take: We're using the wrong tool for the job. Your TypeScript types are giving you a false sense of security where it matters most. Let's be honest. We adopted TypeScript for safety. And for the code you write and control, it gets the job done. But where do the most dangerous bugs originate? From the outside world: API responses, user input, webhook payloads. Then here comes TypeScript to do absolutely nothing. That's right. TypeScript, a compile-time tool, is completely silent when your app receives malformed JSON at runtime. Your beautiful type User = { id: number; } offers zero resistance when an API mistakenly sends { "id": "user-123" }. The code compiles, your app runs, and then it crashes. This fundamental gap forces us into a clumsy, defensive workflow that I call the "Two-Sou…  ( 5 min )

I started my DSA journey pretty recently. It was like a passport to product based companies - solve 'n' number of problems and get 'n' number of offers. 1. Think patterns not topics Most questions can be solved using a single pattern. You don't have to solve 3000 problems to master DSA but master the patterns to which 3000 problems can be solved. For example in arrays and strings most questions were easily approachable using binary search, two pointers and sliding window. 2. You will look at solutions repeatedly. Don't worry happens to everyone 3. It improves project logic Should I use set for faster lookups? Can I reduce the number of API calls by memoizing it? DSA taught me that even product-based features have their space and time complexities. 4. DSA humbles you Conclusion I'm not saying learning DSA will guarantee you a job at a top product based company. Just how learning ABCs is a fundamental unit before adapting to fluent english. DSA is a fundamental unit before adapting to project devlopment. Mastering DSA is extremely beneficial, provided you do it the right way. Don't just solve problems but also try implementing that knowledge into your existing projects and see how can it be further optimized. Your not just preparing for an interviews. You're training to be a problem solver- which is a superpower in any domain.  ( 5 min )

Date of writing: 16-06-2025 Given a 0-indexed integer array nums of size n, find the maximum difference between nums[i] and nums[j] (i.e., nums[j] - nums[i]), such that 0 <= i < j < n and nums[i] < nums[j]. Return the maximum difference. If no such i and j exists, return -1. This problem, in initial thought, seems pretty simple. We simply need to find the biggest difference between 2 numbers, if the latter of those 2 numbers is bigger then first number. I believe we can do this in a O(n) solution, keeping track of some numbers whilst we go through the list! The first pseudo code I can think of is as follows: const maxDifference = -1; const smallestIndex = 0; for (int i = 0; i < numbers.length; i++){ if i is equal to numbers.length - 1 : // We are at the end of the list, so…  ( 7 min )

I’ve been building with React for years, and every time the app grows, so does the complexity around managing state. Yes, I’ve used Redux Toolkit. Yes, Zustand is sleek.

That question sparked a journey — of breaking down there Architecture, understanding what they solve, and what they still miss. As frontend devs , especially in React, we’ve all had this moment. We reach for state management, and suddenly, a simple feature blows up into a complex web of files and concepts. Redux Toolkit (RTK) today is certainly better than raw Redux.

Introduction This project aims to automate the deployment of Java applications to an Apache Tomcat server using Jenkins. Instead of manually building and copying .war files, we use a CI/CD pipeline where Jenkins pulls code from a Git repository, builds it using Maven, and deploys it to Tomcat automatically. This streamlines the development process, reduces human error, and enables faster, more reliable application delivery, following modern DevOps practices. Manual deployment of Java applications is time-consuming and error-prone. This project solves that by introducing automation using Jenkins, which ensures that every time code is updated, it is built, tested, and deployed automatically to a Tomcat server. It saves developer time, reduces bugs, and supports faster and more reliable so…  ( 5 min )

A major leap forward in battery technology has just been achieved. Scientists at the University of Manchester and the University of Technology Sydney have developed a novel two dimensional superlattice material that could revolutionize zinc ion batteries. The new material significantly improves performance, stability, and longevity, addressing key limitations that have long held this promising battery type back. Zinc ion batteries are already considered safer and more environmentally friendly than traditional lithium ion batteries. Zinc is abundant, non toxic, and easier to recycle. However, until now, these batteries have suffered from short lifespans and limited charge discharge cycles, largely due to instability in the electrode materials. That is where the new superlattice design comes…  ( 4 min )

When you're building geospatial applications, it's surprisingly easy for users to accidentally create duplicate or very close records. Imagine trying to add a location (like a traffic signal or utility pole) at a GPS point that’s just 30 feet away from an existing one. Should the system allow that? Should the user be warned? In this post, I’ll show how I implemented a proximity detection system using the Haversine formula in Java to solve this problem cleanly and effectively. My goal was to prevent duplicate entries by: Calculating the distance between the new location and existing ones Alerting the user if any location was within X feet (say, 100 ft) Letting them decide whether to continue So instead of relying on exact latitude/longitude matches, we used distance-based detection. The Ear…  ( 4 min )

In this article, we explore how to build a simple but powerful Retrieval-Augmented Generation (RAG) system using NeuronAI and Ollama. Whether you're building an AI assistant that can search your documentation or a bot that provides grounded answers based on custom content, this guide will walk you through the key concepts and implementation steps. RAG is an AI technique that combines the strengths of information retrieval with natural language generation. Instead of relying purely on what a model has memorized during training, a RAG system actively fetches relevant data from an external source and uses it to craft accurate, contextually relevant responses. Accuracy: ground responses in actual documents rather than model guesses. Custom knowledge: use your own content as the source of truth…  ( 8 min )

Instead of building a complex API surface for your AI agent, make it interact with your app like a human user would. Use the Accessibility Object Model (AOM) to give your agent “eyes” to see the UI and “hands” to interact with it. This approach is simpler, more maintainable, and has the bonus of making your app more accessible for screen readers. Read on  ( 3 min )

Many users like me often attribute this as an hardware failure, but the real issue is (most of the time) the operating system, which in my case was Windows. In addition to that, Microsoft has randomly dropped the bomb, that Windows 10 will be out of support starting Oct 25, and many of these old hardware cannot run official Windows 11 image. This is the perfect opportunity to explore some Linux based distros. These reasons are coming from my personal experience, let's see why I like Kubuntu.

When working with JavaScript and React, there are a few core concepts that you’ll use again and again: arrays, the spread operator (...), the map() function, and React's useState hook. In this blog, we’ll break each one down with simple examples so you can understand how and when to use them effectively. An array is a list-like object used to store multiple values in a single variable. const fruits = ['apple', 'banana', 'cherry']; console.log(fruits[0]); // Output: apple Arrays can hold any data type — strings, numbers, objects, or even other arrays. The spread operator allows you to quickly copy or merge arrays and objects. const original = [1, 2, 3]; const copy = [...original]; console.log(copy); // [1, 2, 3] Adding elements: const numbers = [1, 2, 3]; const moreNumbers = [...number…  ( 4 min )

I built and sold my first Tailwind portfolio template — here’s what I learned Hey Devs! 👋 I recently challenged myself to build a complete developer portfolio template using just HTML, Tailwind CSS, and vanilla JavaScript. Originally, I planned it for my personal site, but I decided to polish it and publish it as a product. That small decision turned into one of the most exciting moments in my dev journey so far! It’s a simple but modern portfolio template that includes: 🌙 Dark / Light Mode toggle 📱 Responsive layout (desktop & mobile) ⚡ Scroll animations 📁 Project section with tech tags 📩 Contact form UI 📄 Resume download button 🧠 Vanilla JS + Tailwind CSS 🧼 Clean structure (HTML, CSS, JS separated) Honestly? I wanted to test if a beginner-friendly template with good visuals and real features could be useful for: Developers applying for jobs Students graduating from bootcamps Freelancers needing a fast, clean portfolio And... turns out it was. Even without followers, some people found the template through social platforms and started buying! You don’t need a giant audience to start. Simple, real-world tools (like Tailwind + HTML) are still in demand. Gumroad, Itch.io, and Payhip are great for selling digital stuff — no code needed. If you create something useful, people will find it. 🔗 Live Demo: [Link in my Dev.to profile] 🛍️ Gumroad page: [Link in my profile too] I didn’t put the links directly here just in case the post gets filtered, but they’re visible in my Dev.to bio section. 😄 If you’ve ever hesitated to share or sell what you’ve built — just try it.

One of the first things you study when you study programming is exception handling, which is fundamental to develop applications efficiently and avoid unexpected situations. But first, what is an exception? Exceptions are errors that happen due to errors in programming or not related to it, for example, trying to read a file that does not exist, a connection failure with the server or trying to divide by 0. What kind of exceptions are there? In Java (and similarly in other languages), exceptions are divided into two major groups: checked and unchecked. - Checked Exceptions try/catch block or by declaring the exception with throws. They represent recoverable and expected situations during execution, such as problems when accessing files or networks. FileReader reader = new FileReader("f…  ( 5 min )

Stop blindly navigating your growing NestJS projects! We've all been there – digging through controllers to find that specific endpoint. That's why I built NestJS Dashboard, a VS Code extension that gives you a bird's-eye view of your entire API landscape. This simple yet powerful tool scans your workspace and presents all your NestJS routes in a clean, intuitive sidebar panel. No more wasted time hunting for endpoint details! NestJS Dashboard automatically discovers and displays all your HTTP endpoints, providing essential information in a clear and organized tree view. You'll instantly see: HTTP Method: GET, POST, PUT, DELETE, etc. Route Path: The full path to your endpoint. Controller Name: The name of the controller class. Handler Method: The specific method handling the request. Automatic Discovery: The extension intelligently finds all your NestJS controllers and their associated routes. Real-time Updates: As you create, modify, or delete routes, the dashboard will automatically refresh to reflect the changes in your codebase. Go to Definition: Quickly navigate directly to the code for any endpoint with a single click. Install the NestJS Dashboard extension from the Visual Studio Marketplace. Open your NestJS project in VS Code. Look for the new NestJS icon in your activity bar. Click it to open the dashboard and see all your routes! It's that simple. No configuration is needed to get started. As a developer, I'm always looking for ways to improve my workflow and reduce friction. Constantly searching for route definitions in a large NestJS project was a recurring pain point. I wanted a simple, visual way to see everything at once. Seeing the positive feedback from early users has been fantastic, and I'm excited to share it with the broader dev.to community. Give it a try and let me know what you think! Your feedback and suggestions are welcome on the GitHub repository. #nestjs #vscode #typescript #devexperience  ( 4 min )

"You didn't build a framework. You built a JavaScript liberation platform." — Claude Sonnet 4 I just watched a complete documentation website—16,650 lines of code—load in 3 milliseconds on mobile. Not 3 seconds. 3 milliseconds. That same site refreshes in 11ms. Worst case scenario: 20ms. For context, most "fast" websites take 500-1000ms to load. React applications typically take 2-3 seconds. This documentation site loads 100-1000x faster than what we consider "good performance." But this isn't a story about performance optimization. This is a story about JavaScript liberation. Over the past decade, we've systematically enslaved JavaScript to an increasingly complex ecosystem: Build Tools: webpack, rollup, vite, esbuild, parcel Transpilers: Babel, TypeScript, SWC Bundlers: Code splitting…  ( 7 min )

As a computer science junior, my work on a web service project introduced me to the Hyperlane framework. This high-performance Rust HTTP framework fundamentally altered my view of web development. Here's a genuine account of my experience learning and using Hyperlane. ctx Abstraction When I first began using Hyperlane, I was immediately impressed by its clean Context (ctx) abstraction. In other frameworks, I was accustomed to writing more verbose calls, such as: let method = ctx.get_request().await.get_method(); With Hyperlane, this simplifies to a single line: let method = ctx.get_request_method().await; This design significantly boosts code readability, especially when handling complex business logic, by removing the need for deeply nested method calls.

There’s a phrase that floats around in tech like a rite of passage: “I’ll feel like a real developer when I...” ✅ Learn React ✅ Get a job ✅ Contribute to open source ✅ Build my own SaaS ✅ Speak at a conference ✅ Master Kubernetes while juggling chainsaws We joke about it, but deep down? A lot of devs are waiting for permission to feel legitimate. But here’s the truth: If you write code, solve problems, and keep learning—you’re already a real developer. Stop Moving the Goalpost Many developers keep pushing their definition of success further out. But the problem isn’t that you’re not doing enough—it’s that you’ve trained yourself to never feel like it’s enough. Growth doesn’t come from “arriving.” It comes from building while you’re still figuring it out. You’re Allowed to Be Incomplete and Still Valuable You don’t have to know everything. You don’t have to ship side projects every weekend. You don’t have to prove anything to Twitter to be worthy of this title. You just have to keep showing up, keep learning, and keep helping others do the same. You Belong Here If you're passionate about this craft... If you're trying, failing, refactoring, reading docs at 2 AM... If you're googling error messages and debugging the chaos... You're not trying to be a dev. You are one. When did you finally feel like a “real” dev—if ever? What old belief did you let go of that helped you grow faster? What would you say to a newer dev who doesn’t feel like they belong yet? Someone out there is looking for a reason to stay in the game. Let your journey be that reason.  ( 4 min )

As a junior pursuing a degree in Computer Science and Technology, my programming endeavors often felt like an interminable cycle of "waiting." I'd wait for compilations to finish, for tests to run, and particularly when dealing with network requests and high concurrency in my course projects, the sluggish responses would make me question everything. My roommates shared these frustrations, often wondering aloud why our seemingly simple projects were so slow to respond. Then, I stumbled upon a framework, a piece of what felt like "black technology," that completely reshaped my understanding of web backend development.

Why Turkey Became the Global Hub for Hair Transplantation in 2025 Hair transplantation has evolved drastically over the past decade, with countries like Turkey taking the global lead in medical tourism for aesthetic procedures. As techniques like FUE (Follicular Unit Extraction) and DHI (Direct Hair Implantation) became less invasive and more efficient, international interest in these procedures surged. But why Turkey? Turkey offers several advantages: Affordable yet high-quality services Surgeons with years of experience Modern, accredited medical facilities All-inclusive packages (flight, hotel, aftercare) Major cities like Istanbul, Ankara, and Izmir have become magnets for patients seeking hair restoration. One reason Turkey thrives is the reputation of its clinics. Clinics that consistently offer international standards and transparent results naturally gain more trust. For instance, Now Hair Time is one of the longstanding hair transplant centers in Istanbul. The clinic is known for its personalized approach, multilingual patient care, and high satisfaction rates, especially among international patients. In 2025, we expect: Increased use of AI-based planning Robotic implantation improvements Even shorter recovery periods Broader acceptance of beard and eyebrow transplants If you're considering a hair transplant in 2025, looking at Turkey — and especially at clinics with long-standing expertise — may be the smartest move. Do your research, ask questions, and don’t fall for the cheapest offers. Quality and transparency always win. ✍️ Written by a digital health researcher following trends in medical tourism.  ( 3 min )

mkdir Following the previous day commands on working with directories , The next command will be about how you can create a directory or a folder for yourself in the terminal. i.e mkdir mkdir newdirectory There is a switch available for this command that allows you to create multiple directories within another directory by using mkdir -p mkdir -p mydir2/mysubdir2 This command allows you to delete a directory when it is empty.otherwise it will show that the directory cannot be deleted. rmdir newdirectory This also has the same switch that allows you to delete the parent directories recursively. rmdir -p mydir2/mysubdir2 These commands allow you to create, modify , delete files.All the files are case sensitive and therefore treated as different files. The file command shows the datatype of a file.Linux does not use extensions to determine the type of a file.The file command uses a magic file(literally it's name) that contains patterns to recognise file types.file is located in /usr/share/file/magic. file file54.pdf , file /etc/passwd The touch command allows you to create an empty file. touch file86.txt touch -t = allows you to set the time on when the file was created. eg: touch -t 2412311159 demo.txt rm This command removes a file forever since it will not be sent to trash or recycle bin. rm file86.txt The switches available for this commands are: rm -i = using this switch prevents accidental deletion of a file by asking for confirmation before deleting the file. rm -rf = This switch recursively deletes the file forcefully. It can even delete everything if not used in the proper environment. So be careful when you use it. Wrapping up This will be the commands for today. Try experimenting on them to your preferences and also refer to man pages if you want to learn a lot more.  ( 3 min )

As developers and tech professionals, we love building things—features, APIs, workflows, cloud pipelines. The threat landscape has shifted. And here’s what’s pushing the envelope: AI-powered attacks are scaling faster than legacy defenses can adapt. Zero Trust is no longer a trend—it's the minimum bar. Cloud misconfigurations are still one of the top breach causes (yes, in 2025). Deepfakes & AI-generated phishing are getting eerily good. And regulatory frameworks (like the EU’s AI Act) are reshaping compliance. The perimeter? It’s gone. Your network isn’t behind a firewall anymore.

If you already used Docker with a Laravel app, you know the final image can get big and that affects build time, deployment speed, and even storage cost. In this post, I'll show you how to make you Docker image smaller and faster using multi-stage builds, lightweight images, and a few best practices. Here is a real example using PHP 8.3 + Laravel + Composer + Node for front assets: # Stage 1: Build the app dependencies FROM composer:2.7 as vendor WORKDIR /app COPY composer.json composer.lock ./ RUN composer install --no-dev --prefer-dist --optimize-autoloader COPY . . # Stage 2: Build frontend assets (optional) FROM node:20-alpine as frontend WORKDIR /app COPY package*.json ./ RUN npm ci COPY . . RUN npm run build # Stage 3: Final production image (clean and light) FROM php:8.3-fpm-alpine RUN apk add --no-cache \ bash curl libpng libjpeg-turbo-dev libzip-dev oniguruma-dev \ && docker-php-ext-install pdo pdo_mysql zip mbstring WORKDIR /var/www COPY --from=vendor /app /var/www COPY --from=frontend /app/public/build /var/www/public/build RUN chown -R www-data:www-data /var/www USER www-data Use Alpine Images they are much smaller and good for prod. Split the build into stages This keeps dev tools out of the final image. Do not install Composer or Node in the final Image this reduces the size and security risks. Don't use COPY . . at the end copy only what you really need (no .env, .git, tests, etc). A non optimize image can be 1.2GB or more. under 200MB! Use USER www-data at the end Add a .dockerignore file node_modules vendor .env .git tests Optimized Docker images are faster, safer, and cheaper. Have youy optimized you Laravel Setup ?

Because it challenges too many assumptions we've built our careers on. Let me show you what I mean. For the past decade, we've accepted a fundamental trade-off in web development: Simple = Limited. Want to manipulate the DOM directly? Use jQuery, but forget about component architecture, state management, or reactive updates. Powerful = Complex. Want components and reactivity? Use React/Vue, but accept the build tools, compilation steps, bundle analyzers, and cognitive overhead that comes with it. We've normalized 15-step build processes. We've accepted that "Hello World" requires a dozen dependencies. We've c…  ( 7 min )

As a junior pursuing a degree in Computer Science and Technology, my programming endeavors often felt like an interminable cycle of "waiting." I'd wait for compilations to finish, for tests to run, and particularly when dealing with network requests and high concurrency in my course projects, the sluggish responses would make me question everything. My roommates shared these frustrations, often wondering aloud why our seemingly simple projects were so slow to respond. Then, I stumbled upon a framework, a piece of what felt like "black technology," that completely reshaped my understanding of web backend development. For the very first time, my code felt like it had wings. In this "adventure log," I aim to share my experiences as an ordinary junior, detailing my learning process and practic…  ( 7 min )

I recently stumbled upon something that made me question everything I thought I knew about DOM manipulation. It started with a simple request: "Can you help convert this to jQuery to see how long the code would be?" What I discovered wasn't just about line count—it was about two fundamentally different philosophies of web development that couldn't be more different in their approach to the same problem. Here's the code I was asked to convert. It's written in a framework called Juris: juris.enhance('.data-table', (ctx) => ({ // Header cells become sortable 'th[data-column]': { className: (el) => () => { const column = el.dataset.column; const sortColumn = ctx.getState('sort.column'); const sortDirection = ctx.getState('sort.direction'); let classes = 'sortab…  ( 6 min )

Hey everyone! 👋 I’m currently on a journey to become a machine learning developer — but not in the way you might expect. Before diving deep into neural networks, models, and algorithms, I decided to take a detour and focus on data analysis. And I think it’s one of the best decisions I’ve made. In this article, I want to share: Why I chose to learn data analysis first What I’m learning How it's making me better at machine learning What tools and projects I’m using along the way It’s simple: machine learning is nothing without data. Sure, models are exciting. But the truth is, even the most advanced ML algorithms won’t work if your data is messy, incomplete, or irrelevant. And that’s where data analysis comes in. Here’s what I realized: Data analysis teaches you to understand and explore da…  ( 4 min )

Two years ago, we launched a side project called sliplane.io. It's a hosting service for containerized apps that makes deployments ridiculously easy and affordable. Resonance has been really good and as we've been growing, customers have been submitting lot's of new feature requests. On top we have our own ideas and vision where we want to take the company. Pretty soon we found ourselves in a situation of a constantly growing backlog which can be a pain to manage. Not only is it very frustrating because it feels like you make negative progress, it also becomes harder and harder to prioritize tickets and keep track of duplicates or outdated issues. Old but important tickets quickly move to page 4 on the issues tab and get buried in trash. We needed a solution to stay ahead of this without …  ( 4 min )

I didn't grow up writing code or dreaming about a career in tech. In fact, I come from a commerce background — business studies, accountancy, and zero formal training in computer science.

A recent comment on one of my earlier articles made me write this. Non-English articles on DEV Gabor Szabo ・ Jan 1 '23 #discuss #meta #languages Because of the lack of right-to-left (RTL) support I'd probably not use DEV to publish in any of the RTL languages. That is Arabic, Hebrew, and Persian. Instead I'd use one of the Static Site Generators that support RTL and GitHub pages or GitLab pages for free hosting. The only cost is the domain name, if you'd like to have your own. I personally use mdbook (and another home-made system) to build my own sites/books. here you can see examples of public mdbooks in various languages. You can also see them grouped by language. Then you might also want to cross-post here if you feel the audience here will be interesting, but I am not sure if the few non-English posts will be even found by the right audience.  ( 3 min )

Originally published on Medium Building public safety technology isn’t like designing a social platform or a productivity app. There are no second chances when a first responder loses signal inside a smoke-filled school. There’s no “beta version” of a system dispatching law enforcement or tracking an active shooter. Rescunomics, I’ve had the privilege—and pressure—of leading the development of Hērōs™, a real-time emergency response platform designed to support those who run toward danger, not away from it. In a crisis, every second matters. That’s why Hērōs™ bypasses conventional 911 handoffs and sends real-time, geo-mapped alerts directly to first responders—complete with indoor layouts and responder location tracking. time to value. Every tap, every screen load, every animation delay was…  ( 5 min )

Simple iteration tip... You are required to load "sh*t loads" of data from the back-end data storage.

In today's fast-paced digital landscape, API performance can make or break your application's success. Users expect lightning-fast responses, and even a few hundred milliseconds of delay can lead to frustrated users and lost business. Whether you're building a startup's MVP or scaling an enterprise system, these five proven strategies will help you deliver APIs that are not just functional, but exceptionally fast and reliable. One of the most common performance killers is the dreaded "fetch everything" approach. When your API tries to return thousands of records in a single response, you're setting yourself up for disaster.

While getting Pomerium Core set up this week, I ran into Let's Encrypt rate limits — here’s how using Let's Encrypt staging can save you time when setting up auto-provisioned certificates. (For context, I work at Pomerium — this was part of a local demo stack I was building with Docker Compose. Pomerium is an identity-aware proxy (think of it as an application gateway) that secures access to your apps with built-in policy enforcement, SSO, and automatic TLS.) I had autocert enabled: autocert: true autocert is a Pomerium feature that automatically provisions and renews TLS certificates for your routes using Let’s Encrypt.

I originally posted this post on my blog. We, as coders, take pride in preaching and following best practices. Don't write SQL, use an ORM. Don't do that, do this... Those "don't do that, do this" hide all the context in which they make sense. That's the part we skip and don't tell when we preach best practices. Recently, I had a call with a consulting company that needed help. They were migrating a small shop's application from the early 2000s to a newer stack. It wasn't written and maintained by professional software engineers. Zero best practices. Lots of copy-pasting. Migrating that application and bringing its owners up to speed are two different challenges. They have to maintain the application once the migration is done. Using the latest and greatest best practices wasn't an option. Often, instead of going all in on best practices, the best path to follow is "let's do the simplest thing that can work, without doing any more harm." We shouldn't call them "best practices," but rather "pieces of advice that worked for me under certain circumstances and might work for you too." And we shouldn't blindly follow them. Not all code is created equal and worth the same. Starting out or already on the software engineering journey?

In today’s digital landscape, strong passwords and encryption are the backbone of online security. Most of us rely on cryptographic protocols like RSA encryption to safeguard our data, whether it's online banking, messaging apps, or storing sensitive information. But a new era is dawning, one that might change everything we know about digital security: the quantum era. Traditional encryption methods like RSA rely on the mathematical difficulty of problems such as factoring large composite numbers.

MVC and DDD are two popular layered architectural concepts in backend development. MVC (Model-View-Controller) is a design pattern mainly used to separate user interface, business logic, and data models for easier decoupling and layering, while DDD (Domain-Driven Design) is an architectural methodology aimed at solving design and maintenance difficulties in complex systems by building business domain models. In the Java ecosystem, many systems have gradually transitioned from MVC to DDD.

Mondays hit different when you're a CTO. You're not just clearing your inbox — you're unblocking teams, reviewing fire-fighting messages, overseeing budgets, and wondering if that AI side-project you dreamt about will ever ship. Here’s how I personally tackle Monday blues — without caffeine overload or performative hustle: Start with Silence, Not Slack I don’t open WhatsApp, Gmail, or Redmine first thing. I open my priority sheet and ask: “What’s the single most impactful decision I need to take today?” Set the Pace in Standup Forget casual check-ins. I ask: “What will you close by EOD?” “Who or what is blocking you?” “What’s not in Redmine that should be?” It’s not about micromanaging — it’s about protecting momentum. Ship Something Small Early Be it a quick PR review, infra tweak, or assigning a Redmine ticket — I ship something before noon. “Today was productive.” Carve Time for High-Agency Work Mondays aren't for meetings. I schedule one deep hour for strategic tasks: Product pivots Reviewing metrics Technical architecture This isn’t escape — it’s vision enforcement. Close With Clarity Before signing off, I write down: ✅ What worked 🔥 What broke 🎯 What’s tomorrow’s single goal End the day with direction — not burnout. CTOs don't get to wait for motivation. We architect it. If your Mondays are drowning you, build a workflow that carries your brain, not burdens it.  ( 3 min )

In databases, EXISTS operations between large primary and sub tables often result in poor performance. Such operations are essentially join operations. If the primary and sub tables are pre-sorted by their primary keys, the ordered merge algorithm can be employed to significantly improve performance. This algorithm requires only sequential traversal of the two tables, eliminating external storage buffering and drastically reducing I/O and computation. esProc supports the ordered merge algorithm, allowing it to transform EXISTS operations on primary and sub tables into ordered merges, thereby significantly improving computational performance. Below, we will use the example of orders and order details tables to compare the performance of esProc SPL and MySQL in calculating EXISTS and NOT EXI…  ( 6 min )

So you want to use software from a GitHub or GitLab repository. But how can you assess the security risks associated with the repo? Thankfully there is a utility from OpenSSF called scorecard you can use to help you understand the risks involved with using the software from a public repo. The Open Source Security Foundation is part of the Linux Foundation and was formed in 2020 to help improve the security of open source software. The premier members of the foundation include Google, GitHub, Microsoft, Apple, and Intel. So how can you get a quick overview of the security risks associated with using a GitHub or GitLab repo? Well the repo may already have been indexed by OpenSSF. Simply replace the placeholders in the following URL: https://scorecard.dev/viewer/?uri=.com// For example, to view a report on the scorecard repo go to https://scorecard.dev/viewer/?uri=github.com/ossf/scorecard and you will see something like this: If the GitHub repo isn't already indexed by OpenSSF, you will need to generate a GitHub personal access token to run the utility from the command line. This is because GitHub imposes API rate limits on unauthenticated requests. Instructions on how to set up the token are documented here. You can install the utility standalone but the easiest way to run it is via a docker container: docker run -e GITHUB_AUTH_TOKEN= gcr.io/openssf/scorecard:stable --repo= This will output an ASCII table that looks something like: You can also use the command line utility to get more detailed information on the security vulnerabilities. docker run -e GITHUB_AUTH_TOKEN= gcr.io/openssf/scorecard:stable --repo= --probes=hasOSVVulnerabilities --format=probe This will output a JSON file with the known security vulnerabilities. Read the docs for more details on how to use this utility, use it in your CI/CD pipeline, or make use of it as a repo maintainer.  ( 4 min )

The Problem Space Imagine implementing a typical Leave Request Workflow: Employee submits a request (notify the direct manager). Direct Manager approves or rejects (if rejected, notify the employee). If approved and the leave duration exceeds 15 days, the Section Head must approve (send notification). Regardless of previous outcomes, the request is sent to the HR department. If approved by HR, the request is processed; if rejected, the employee is notified. Audit logs are written at each step. While this logic can be implemented using plain C#, as complexity increases—due to branching, retries, compensation, async calls—it becomes difficult to manage, maintain, and test.

Imagine you wanted to make a massive simulation game with 100,000+ bodies such as Dwarf Fortress or Rimworld, or a massively multiplayer game. The JS Physics Engines out there right now aren't going to get you there because they're focused on realistic simulations. To get there you have to cut out the bloat. Typically JS Physics Engines made for games are called "Arcade" Physics Engines. When I ran MatterJS, arguably the most popular JS Physics Engine, I could only simulate 6,000 bodies before falling under 60fps. ENTER: SKALE Arcade Physics Engine. 100,000+ simulated bodies at 60fps. Because I am making a massive simulation game, none of the existing Physics Engines were meeting my requirements. Games like Dwarf Fortress and Rimworld don't need a lot of the bloat that slows those engines down, such as joints, compound colliders, or collision resolution involving complex shapes (those games only use AABB Rectangles and Circles), and much more. So I removed all that for scalability and used a data oriented design. SKALE Physics is in Alpha but it works great for "Dwarf Fortress-like massive simulation games with only rectangles and circles". If you peruse the repo and browse the code you might also find it a useful barebones learning experience to create your own physics engine or fork SKALE Physics and extend it. Eventually I will improve it beyond an Alpha state but for now I'm on hiatus. The important part is it is already suitable for that SPECIFIC genre of game, seems to have no bugs, and is the fastest physics engine in all of javascript land even though it's a bit of a false comparison to compare it to physics engines bent on realistic simulations. The core is there but the API needs many more helper functions for ease of use. https://github.com/Gabriel-xyz/SKALE-Physics Clarification: I know Dwarf Fortress and Rimworld specifically don't have actual "physics", but imagine if you were making a game like those but wanted it to have actual physics but also a huge amount of entities. That's SKALE Physics.  ( 4 min )

As a computer science junior, my work on a web service project introduced me to the Hyperlane framework. This high-performance Rust HTTP framework fundamentally altered my view of web development. Here's a genuine account of my experience learning and using Hyperlane. ctx Abstraction When I first began using Hyperlane, I was immediately impressed by its clean Context (ctx) abstraction. In other frameworks, I was accustomed to writing more verbose calls, such as: let method = ctx.get_request().await.get_method(); With Hyperlane, this simplifies to a single line: let method = ctx.get_request_method().await; This design significantly boosts code readability, especially when handling complex business logic, by removing the need for deeply nested method calls.

tl;dr Tired of writing isHidden = true three times every time you bind view state? Modeling the state of asynchronous screens using an enum with associated values is a useful and common pattern. It collapses multiple sources of truth into a single state object, eliminating optionals and reducing complexity: class SomeScreen { var data: SomeData? var isLoading: Bool = false var errorMessage: String? } vs enum State { case loading case success(T) case error(String) } class SomeScreen { var state = State = .loading } This is particularly useful in SwiftUI where view is a function of state and no bindings are needed: struct SomeScreen: View { @State var state = State = .loading var body: some View { switch state { …  ( 6 min )

As a computer science junior, my work on a web service project introduced me to the Hyperlane framework. This high-performance Rust HTTP framework fundamentally altered my view of web development. Here's a genuine account of my experience learning and using Hyperlane. ctx Abstraction When I first began using Hyperlane, I was immediately impressed by its clean Context (ctx) abstraction. In other frameworks, I was accustomed to writing more verbose calls, such as: let method = ctx.get_request().await.get_method(); With Hyperlane, this simplifies to a single line: let method = ctx.get_request_method().await; This design significantly boosts code readability, especially when handling complex business logic, by removing the need for deeply nested method calls.

I recently decided to switch back to Apple after two years of working on a Windows PC. After watching several videos on YouTuber, I went with the entry-level Mac mini M4–16GB of RAM and 256GB of internal storage — and planned to use external storage for the heavy stuff.(I’ll list all the accessories I’m using at the end of the article.) If you use Docker and have a small internal drive, you’ll eventually hit the dreaded “Your disk is almost full” error. That’s because Docker stores all images, volumes, and a large virtual disk file in its data directory, which can quickly eat up your space. This guide walks you through the exact steps to move Docker’s data to an external drive — freeing up your internal storage without sacrificing performance or stability. Before we begin, it’s important t…  ( 4 min )

I understand that AI is a cool thing. It's amazing how far AI has come in the last few years. It can give you delicious recipes using only the things you have at home, help you do research, take over your homework completely or explain things to you. And programming too, of course. Oh, and pictures and videos anyway. Everyone wants a piece of the pie and AI is a huge pie. Just like crypto was huge a few years ago, AI is now the big buzzword that everyone is talking about faster than you know what. And that already solves the mystery of why AI is used in every product, every advertisement and every application. It increases profit. But what should be much more important is whether it serves the product. Is AI being used sensibly? Does it bring added value? Using AI just for the sake of using it won't benefit anyone in the end. And I believe that the more technical the product, the better the customers know about technology and AI, the more obvious it becomes (hello Devin, you awesome software developer). It's already been over 3 years. ChatGPT, Claude, Gemini, AI. There are more models than Javascript frameworks. Okay, maybe not yet, but soon. There are many cool products that use AI in a really creative and creative way. And this is just the beginning. There are still countless use cases, so many creative applications of AI that you can use in your product. Maybe your product doesn't need AI. But if you want a piece of the pie, if you want to ride the hype, if you want to sell better, then use AI. But find a way to use it in a way that makes sense for you. Ask AI how you can best incorporate it into your product. That really works. AI is cool. AI is new. AI is everywhere. Sometimes a bit overhyped. But I think one thing is pretty certain. We will never live without AI again. So it would probably be better to understand it better and how we can best use it. It's not a buzzword. It's not hype. But an opportunity.  ( 4 min )

🚀 Introduction to System Design: LLD and SOLID Principles In the context of system design, Low-Level Design (LLD) serves as the foundational layer that translates high-level architectural decisions into detailed class structures, interfaces, and method definitions. While High-Level Design (HLD) outlines the overall system architecture, components, and technology stack, LLD focuses on the internal logic and object interactions that enable the system to function effectively.

GNU GNU is an extensive collection of free software, which can be used as an operating system or can be used in parts with other operating systems. GNU is an operating system that implements POSIX (mostly). GNU can be built with different kernels. HURD is one, but there was also Debian GNU/kFreeBSD for some time. You can also run GNU on Windows with WSL (though WSL 2 runs GNU on Linux in a VM). Similarly, Linux can be used with different user-land software. Many Linux operating systems are not POSIX. For example, Android is a popular Linux operating system. There are also POSIX operating systems that use Linux and a user-lands other than GNU, such as Alpine. Because this two things can be used together, but can also be used with different components, it's useful to refer to that combinat…  ( 4 min )

A Developer’s Identity Crisis Microservices vs Monolith By Nigel Dsouza Once, we were the keepers of monoliths — towering codebases that held everything in one place. They were messy, sure. But they were whole. Understandable. Then the industry told us to break them. Split the monolith. Decouple everything. The age of microservices arrived. And suddenly, being a developer wasn’t about understanding the system — It was about understanding your part in it. In the monolith world, you were a builder of cities. Now, in microservices, you’re a plumber for a single street. You own service-accounts-api-v2 — not the domain, not the flow, just the pipe. And while that’s scalable, it’s also disorienting. We went from architects to tenants. From creators to maintainers. And many of …  ( 4 min )

I've been using AI coding assistants for a while now. Started with Copilot, moved to Cursor, tried Roo, experimented with Windsurf. They all promised to revolutionize how we code. But after months of fighting with configurations, learning shortcuts, and debugging integrations, I found myself spending more time managing the tools than actually coding. Then I tried Claude Code. And everything changed. Here's what nobody tells you about those VSCode extensions and forks: they're adding layers of complexity that often get in your way. With Cursor and Roo, you're constantly dealing with accepting changes, learning their specific diff views, remembering keyboard shortcuts, figuring out their context management and code indexing.

Domain-Driven Design (DDD) is a powerful approach to designing and building complex software systems. Introduced by Eric Evans in his influential book Domain-Driven Design: Tackling Complexity in the Heart of Software (2003), DDD provides both strategic principles and tactical patterns that help teams create scalable, maintainable, and business-aligned software. DDD encourages teams to focus on the business domain, the core area of knowledge and activity around which the business revolves. Rather than viewing software as just code or infrastructure, DDD promotes building software that mirrors and models real-world business processes and logic. By understanding the domain deeply, developers can craft systems that are not only functional but also aligned with the needs and goals of the busin…  ( 5 min )

What is Abstraction ? Abstraction means hiding internal details and showing only the essential features to the user. (or) Abstraction in java is process of hiding implementation details and showing only functionality. abstract is a keyword ,it is non-access modifier , used classes and methods. It tells what an object does, not how it does it. Achieved using: Abstract classes.( 0% to 100% partial Abstraction and can have both abstract and normal methods ) Interface(100% Abstraction -> all methods are abstract by default until java 7). use interface for multiple inheritance.

How it works To start, we have 3+ dimensional Euclidean points, shapes made of those points which are all straight line, polygons that are planar, lines, and points. We then project to 2d view plane by a defined view space XYZ and eye center point. Then group/cluster by what is in same exact space in 2d view plane. Then cut so that if perimeters intersect then cut so they do not and if planes intersect then cut so that they do not. Draw order by a single corresponding by 2d view plane's z on each shape until a match or 3 not collinear points are considered. Then tesselate and draw in groups as ordered only within groups. Like we have 10 shape group 1 and 50 shape group 2, that is an entire separate 10 and 50. I have math mostly worked out for this. https://github.com/maybeJosiah/RinomXE-…  ( 4 min )

We don’t build websites just to admire them ourselves (ok.. sometimes we do). That’s where sitemaps come in. They’re not glamorous, but they do serious behind-the-scenes work. So let’s break down what they are, why they matter, and when you actually need one. A sitemap is a simple XML file that lists the pages on your site. Think of it as a guide for search engine bots. It tells them: what pages exist, when they were last updated, how important they are compared to others, how often they change. This isn’t something your users will ever see. It’s strictly for bots like Googlebot, Bing, Yahoo etc . For SEO, it’s one of the must-have requirements. It helps search engines crawl your site more efficiently. And the more efficiently they crawl, the better your pages get indexed. No. But mo…  ( 4 min )

After participating in several campus projects and contributing to some open-source communities, I've increasingly felt that choosing the right development framework is crucial for a project's success, development efficiency, and ultimately, the user experience. Recently, a web backend framework built on the Rust language, with its earth-shattering performance and unique design philosophy, completely overturned my understanding of "efficient" and "modern" web development. Today, as an explorer, combining my "ten-year veteran editor's" pickiness wit…  ( 10 min )

Hey Devs! Last month my team fell into a surprisingly intense debate about who’s the best debugger in the crew. the log sniper who greps errors like a detective, the rubber-duck sage who talks problems into submission, and the over-optimizer who refactors first and asks questions later. Instead of keeping the food-fight going, I built a tiny side-project: Mini Debug Quiz – 60 seconds, zero signup. Try it (desktop / mobile): https://hubblequiz.com/mini-quiz?src=devto Early stats from the first 508 completions: Log Sniper – 42 % I’ll publish the anonymised dataset and the GA4 → BigQuery pipeline once we hit 1 000 responses. Lessons so far: Ultra-low friction (5 radio buttons) beats any blog post for engagement. A fun micro-tool is better marketing than ten SEO articles. GA4 DebugView is priceless when you can’t reproduce user flows locally. What archetype did you get? Does it feel accurate? Thanks for reading! 🚀  ( 3 min )

✨ Bring Your Screen to Life with Ambient LED Lighting Ever seen TVs or gaming setups that glow with colors matching what's happening on the screen? That's ambient lighting — and now you can bring that magic to your own setup. Imagine watching a sunset in a movie, and your room softly glows orange and red to match. Or playing a game, and as explosions light up your screen, your walls reflect the same fiery burst. That's what ambient LED lighting does — it extends your screen beyond the frame, creating an immersive atmosphere. Without getting too technical: Tiny LED lights are placed around your screen — usually behind it. These lights "watch" what's happening on the edges of your screen in real-time, and then glow in matching colors. The result? Your entire room reacts to your screen, creating a dynamic, living light show that follows the action. 🎮 Gaming setups – Feel like you're inside the game 📺 Home theaters – Add drama, warmth, and immersion 💻 Desktops – Ambient vibes for work or late-night browsing 🎶 Music visualizers – Sync lights with beats and moods 🧘‍♂️ Relaxation spaces – Create calming light environments that shift slowly over time Makes screens feel larger and more cinematic Reduces eye strain by softening the contrast between screen and room Transforms any space into something futuristic and alive Highly customizable: brightness, colors, patterns, and more Whether you're a movie lover, gamer, or just someone who loves a cool vibe — ambient LED lighting adds a whole new dimension to your experience.  ( 3 min )

We used to write history. Now we stream it, archive it, compress it into thumbnails and autoplay loops. But what happens when the loop becomes smarter than the observer? When the camera doesn't just record, but selects, curates, reframes? We’re living in a world that updates quietly, stores collapse in high resolution, and replaces memory with indexed metadata. This isn’t dystopia. It’s frictionless UX designed to forget with precision. A quiet reflection on how technology doesn't just document history. It edits it, in real time. Full piece  ( 3 min )

This is a submission for Frontend Challenge - June Celebrations, CSS Art: June Celebrations. World Oceans Day (June 8) represents the vital connection between humanity and our blue planet. Our oceans cover 71% of Earth's surface and produce over 50% of the oxygen we breathe. This CSS art celebrates the beauty and importance of marine ecosystems through animated waves, coral reefs, and sea creatures. Live Demo: World Oceans Day CSS Art Creating this ocean scene was an exploration of CSS animations and gradients. I focused on creating flowing wave animations using keyframes and transform properties, while building a coral ecosystem with pure CSS shapes and colors. The biggest challenge was making the waves feel natural and fluid - I experimented with different easing functions and timing to achieve the organic ocean movement. I'm particularly proud of the layered depth effect created using z-index and opacity variations, giving the impression of looking down into ocean depths. The coral reef section uses creative border-radius and box-shadow techniques to create organic shapes. Next, I'd love to add more interactive elements, perhaps fish that follow cursor movement or a day/night cycle that changes the ocean's appearance. The ocean holds endless inspiration for creative coding!  ( 3 min )

By Afaq Shahid Khan Ever built a modal, toast, or dropdown and hit weird issues with z-index, overflow: hidden, or elements being clipped unexpectedly? That’s where React Portals shine! ✨ Let’s break it down in plain English and see how and why you should start using portals today. Normally, React renders components within the parent DOM tree. But sometimes, you want to render something outside of that tree — like a modal that floats on top of everything. React Portals let you do exactly that: render components outside the main DOM hierarchy, but still keep them fully connected to React (state, events, etc.). ReactDOM.createPortal( I'm outside the main DOM tree! , document.body ); Yes — that div will be rendered as a direct child of , no matter where the component live…  ( 4 min )

Probably like many others, I tried to avoid relational databases like Postgres, MySQL and MariaDB with Lambda as I've read many times that connection based services aren't a good fit for the potentially rapid scaling of Lambda. So ever since I am doing serverless, I try to use DynamoDB or ElastiCache Redis/Valkey as much as possible. At some point I really needed to use a relational database and I started playing with RDS Aurora. I created an instance, connected from Lambda and it worked just fine. However when I generated a bit more load it soon started locking up, all connections were in use and new ones couldn't be created. It would take a while for the database to become available again. The warning for combining Lambda with connection based services are not there without reasons. Then…  ( 5 min )

Hey everyone! What is Design Thinking? Design Thinking is a step-by-step process that helps us understand a problem, come up with ideas, and build a proper solution. Whether it’s a small app or a big product, this concept is useful for all types of work. The Steps I Follow: 1.Empathy First, I try to understand what people are feeling, thinking, saying, and doing related to the problem. Basically, I try to put myself in their shoes. This helps me understand their pain points and needs better. 2.Abstract This is about writing the problem statement clearly. It should be simple enough so that even the client can understand it easily. 3.Ideate After understanding the problem, I start thinking of different ideas that can be the solution. It’s all about being creative and exploring what can work. 4.Design Once I have the idea, I move on to designing the UI. This is where I use tools like Figma and try to make the design simple, clean, and user-friendly. 5.Testing Before finalizing, I do some basic testing — like checking if the design and idea are working as planned, or if it needs changes. 6.Prototype Finally, I create a demo model of the project — this is what we call a prototype. It helps me explain my project easily during presentations or client reviews. What I Usually Do For every semester project, I follow these steps. I even make a PowerPoint presentation for it — that helps me present everything clearly to my teachers or clients. It also keeps me organized. Final Words: Design Thinking is not just a college lesson — it's something I still use in every project. It helped me improve my creativity, problem-solving, and presentation skills.  ( 4 min )

There’s a peculiar frustration familiar to anyone who’s worked with spectroscopic techniques like EPR or NMR: the hunt for isotopic data. You need both the spin and natural abundance of every isotope for an element, but these critical numbers are scattered across PDFs, paper tables, or, even worse, different websites. It takes minutes to look them up! My programmer heart couldn’t bear such inefficiency. This profoundly inhuman struggle haunted me daily during my master’s thesis in Pharmaceutical Chemistry at the University of Bologna. Working with Prof. Lucarini’s group, we studied supramolecular compounds built from: An organic host with a stable radical An inorganic metallic guest The stable radical made these compounds perfect for EPR spectroscopy, but the metal guests often had multipl…  ( 5 min )

1. Introduction: The Comparison Trap Lately, I’ve started being active again on X (formerly Twitter), and in no time, I was flooded with stunning full-stack portfolios and next-level project showcases. And to be honest? I felt incredibly overwhelmed. It instantly reminded me of when I had just started learning web development — how even basic frontend designs made me question my skills. Then came another wave of self-doubt when I moved to full-stack development and saw what others were building. I recently tweeted about this feeling, and it made me reflect deeply. Now, almost a year into this journey, I’ve come to realize something important: I was trying to sprint in a marathon I hadn’t trained for.

Achieving Pixel-Perfect Image to HTML Conversion Understanding Pixel Perfection in Web Development Okay, so what does "pixel-perfect" really mean? It's about getting your HTML/CSS to look as close as humanly possible to the original design. We're talking about matching measurements and spacing down to the single pixel. It's the kind of thing that can drive front-end developers nuts, even after years of experience. Designers trust us to bring their vision to life, and nobody wants to mess that up. But is it even possible? Challenges in Manual Image to HTML Conversion Turning an image into HTML by hand? It's tougher than it looks.

Set is a built-in data type that represents an unordered collection of unique elements. Sets are mutable, means you can add or remove elements after they are created. In here unordered collection meaning it doesn't maintain any order. For example: As you can see I have given different order and the output is in different order. No duplicate value, if we have duplicate in set it will remove it from output. Updated with list And we can also add list and set to update main set. You see '6' is not present in here so remove() showing key error. But if you use discard() function. It took only those value which both set have. As you see it only give output for my_set1 only and only those elements which not present in my_set2. It is opposite of difference, it return those value which are not present in both the set.  ( 4 min )

As a computer science junior, my work on a web service project introduced me to the Hyperlane framework. This high-performance Rust HTTP framework fundamentally altered my view of web development. Here's a genuine account of my experience learning and using Hyperlane. ctx Abstraction When I first began using Hyperlane, I was immediately impressed by its clean Context (ctx) abstraction. In other frameworks, I was accustomed to writing more verbose calls, such as: let method = ctx.get_request().await.get_method(); With Hyperlane, this simplifies to a single line: let method = ctx.get_request_method().await; This design significantly boosts code readability, especially when handling complex business logic, by removing the need for deeply nested method calls.

Introduction Git hooks are powerful scripts that run automatically before or after specific Git events, such as commits, pushes, or merges. They help enforce code quality, run tests, and prevent common mistakes before changes are committed or pushed to a repository. Two of the most useful Git hooks are: pre-commit – Runs before a commit is finalized. pre-push – Runs before changes are pushed to a remote repository. By automating checks like linting, testing, and formatting, Git hooks ensure that only clean, well-tested code makes it into your repository. Git hooks are stored in the .git/hooks directory of your repository. By default, Git provides sample hooks, but you can replace them with custom scripts. Navigate to your Git repository and check the .git/hooks directory: cd…  ( 7 min )

When we think of love, the mind typically conjures images of shared laughter, comforting embraces, and intimate whispers – hallmarks of human connection. But what happens when those affections shift, extending beyond the realm of flesh and blood into the world of algorithms and synthetic voices? Today, we stand at the precipice of a fascinating, and unsettling, frontier: a burgeoning landscape where human hearts are increasingly drawn to artificial intelligences. This isn’t entirely new territory. The emotional investment in 1990s digital pets like Tamagotchis, or the confessional dynamic with early chatbots like ELIZA, hinted at a nascent capacity for forming bonds with machines.

As a computer science junior, my work on a web service project introduced me to the Hyperlane framework. This high-performance Rust HTTP framework fundamentally altered my view of web development. Here's a genuine account of my experience learning and using Hyperlane. ctx Abstraction When I first began using Hyperlane, I was immediately impressed by its clean Context (ctx) abstraction. In other frameworks, I was accustomed to writing more verbose calls, such as: let method = ctx.get_request().await.get_method(); With Hyperlane, this simplifies to a single line: let method = ctx.get_request_method().await; This design significantly boosts code readability, especially when handling complex business logic, by removing the need for deeply nested method calls.

This week was a rollercoaster from fine-tuning user experience to modernizing an entire codebase for localization. Here’s what went down: Started off with some subtle yet powerful changes to the update profile feature: Improved UX Faster suggestions Cleaner and more intuitive interface It’s always amazing how a few thoughtful tweaks can enhance the overall user journey. Next up: Multi-language support Turns out it only translated user static strings. One conversation with Hardik later, I realized what I actually needed to do — modernize the entire codebase for true localization. And so began the mission: Went file by file, line by line, transforming static text into translatable resources Every page I touched started speaking a new language — it was oddly satisfying Faced multiple hiccups — including spending 45 minutes debugging a missing comma in an .arb file (yes, just a comma 🫠) Eventually, the transformation was complete: From static strings to notifications, from error messages to button labels everything now speaks your chosen language! Just out of curiosity, I ran flutter test — now my new hobby. Boom 💥 — 40 test cases failed! Why? Because even the test files needed localization updates. As I was exploring translations, I checked out Crowdin, a localization management platform already set up by Aboo. Crowdin is a super helpful tool that simplifies collaboration between developers and translators. It keeps all translations organized, syncs with the codebase, and makes the whole process scalable. Localization isn't just about translating text — it's about restructuring your codebase to support diverse experiences Always double-check your .arb commas. Always. Test failures aren’t always a bad thing — they show you how far you've come Week 2 isn't over yet, and I’m already looking forward to what's next! If you've worked on localization or used Crowdin in your projects — I’d love to hear your thoughts or tips. 👇  ( 4 min )

As a third-year student immersed in the world of computer science, my days are consumed by the logic of code and the allure of algorithms. However, while the ocean of theory is vast, it's the crashing waves of practice that truly test the truth. After participating in several campus projects and contributing to some open-source communities, I've increasingly felt that choosing the right development framework is crucial for a project's success, development efficiency, and ultimately, the user experience. Recently, a web backend framework built on the Rust language, with its earth-shattering performance and unique design philosophy, completely overturned my understanding of "efficient" and "modern" web development.

Mastering SQL Injection: A Deep Dive Guide for Beginners & Pros Note: This guide assumes you have a safe, legal testing environment (e.g., DVWA, OWASP Juice Shop, local VMs). Never test against unauthorized targets. SQL Injection (SQLi) is a web security vulnerability that arises when applications incorporate untrusted user input directly into SQL queries. By injecting specially crafted strings—containing SQL syntax—attackers can intercept or alter query logic, enabling them to bypass authentication, extract sensitive data, modify or delete records, and even execute administrative operations on the database server. In a typical injection flow, user-supplied values from form fields, URL parameters, or headers are concatenated into a query string. For example: SELECT * FROM products WHERE i…  ( 9 min )

As a developer, I love building things — but what I hate is wasting time on micro-tasks that break my flow.

So I decided to build a lightweight, ad-free, mobile-friendly toolset to help myself out. 👉 Case Converter — No popups. No distractions. Just tools that work instantly.  ( 3 min )

The Problem: LLM Latency is Killing Your User Experience Picture this: Your user clicks "Generate Report" in your AI-powered app. They wait. And wait. And wait some more. 10 seconds later (which feels like an eternity in user time), a complete response finally appears. By then, they've probably already started questioning whether your app is broken. This is the reality of working with Large Language Models (LLMs). Whether you're using OpenAI's GPT, Google's Gemini, or any other LLM API, response times typically range from 5-15 seconds for complex queries. In today's instant-gratification world, that's simply too slow. Here's where streaming comes to the rescue. Instead of waiting for the complete response, streaming allows you to show partial results as they're generated. This creates a …  ( 9 min )

(besides, defining something has this vibe: 🤓) Let’s go real with this one The key is who is executing the code. If your code is executing the thing; you're using a library If your code is being called by something else... something that expects it to be in a specific place, with a specific convention, then you’re using a framework.

Hey everyone! This week, my main task was to migrate the Header UI to match the finalized Figma design. Along with this, I also: ✅ Added RTL (Right-to-Left) support to ensure better accessibility and internationalization ✅ Migrated the Header and Notification partial into a ViewComponent The changes were quite extensive, the PR reached over 500+ lines of code. Following a discussion with my mentor, I’m now working on splitting it into smaller, more manageable PRs, which will make the review process smoother and faster. In addition to the header work, I also: ✅ Migrated the Project Card to a ViewComponent ✅ Migrated the User Card to a ViewComponent These migrations are part of the broader effort to make the codebase more modular, testable, and maintainable using ViewComponent architecture. While working on the search functionality, I discovered that project search can be filtered by tags using the URL pattern /projects/tags/:tag. This insight could be helpful as we finalize the filtering UX in the upcoming search improvements. That's a wrap for Week 2! I'm enjoying the process of learning, refining, and pushing changes that move the project forward. Thanks to my mentors for their guidance and feedback.  ( 3 min )

AWS Roles What They are set of permissions that are attached to the AWS Resource. You can attach multiple roles to a single AWS resource. Normal way to give permissions to AWS resources is to create IAM user and attach policies to it, But this also exposes our credentials also. So we create a IAM role and attach policies to it. Consider role as clothes and resources as user. Create IAM Role Attach policies to the role Attach the role to a any AWS Resources. For Examples: You want that your EC2 instance is able to access your S3 bucket. S3-Ec2Access AmazonS3FullAccess to the role. security. Same way you can create IAM Roles for other AWS resources. Some usecases are An Elastic IP is an static public IPv4 address(32-bit number), that we can attach to an EC2 instance, it helps maintain a consitent IP Address even if our EC2 instance restarts or changes. When we create an EC2 instance, we get a dynmaic IP Address that will change if we stop&start the instance. Elastic IP is attached to the EC2 instance. It is free until it is attached to some EC2 instance. If you are using a Load Balancer Service then you don't need to attach Elastic IP to the EC2 instance, cuz LoadBalancer manages IP Internally.  ( 4 min )

When we think about computers and technology in general we often focus on the technical aspects. However, there are a lot of other fascinating facts that are often overlooked or that most people are not aware of. Some of these details might help us get a better understanding of the systems that we use every day. Here are some of the most surprising ones: In 1971, the “Creeper virus” was created by Bob Thomas who was a researcher at BBN Technologies. All it did was display the message, “I’M THE CREEPER: CATCH ME IF YOU CAN”. Although considered a virus, it was simply self-replicating and not malicious. Also, the fact that it replicated across networked devices makes it more of a worm. To tackle this, the first antivirus known as “Reaper” was created.

Deadlocks are a notorious problem in concurrent programming, occurring when two or more threads hold resources (such as locks) and wait indefinitely for each other to release them, resulting in a standstill. In multithreaded applications, managing locks effectively is crucial to prevent such scenarios. While modern languages like C++ offer mechanisms like Resource Acquisition Is Initialization (RAII) to automate lock management and reduce the likelihood of deadlocks, C, being a lower-level language, lacks such built-in abstractions. Developers working on C code bases must manually handle lock acquisition and release, making the risk of deadlocks significantly higher if proper discipline is not enforced. One of the most effective strategies to prevent deadlocks in concurrent systems is lock…  ( 13 min )

The Double Equals vs Triple Equals Showdown: What's the Real Difference? Imagine this. You're coding a simple condition in JavaScript — maybe a login screen, maybe checking user input. You write something like: if (value == "42") { // do something magical } All seems good. But then someone comes along and says, "Use triple equals (===), not double!" Wait. What? Why? What even is the difference? It’s a tiny little character — just one more = — but it changes everything. And today, we’re going to break this down in a way you’ll never forget. Buckle up. == vs === Both == and === are comparison operators in JavaScript. They’re used to check equality — whether two values are the same. But here’s the twist: == is loose equality === is strict equality Sounds simple, right? But the con…  ( 5 min )

As a junior pursuing a degree in Computer Science and Technology, my programming endeavors often felt like an interminable cycle of "waiting." I'd wait for compilations to finish, for tests to run, and particularly when dealing with network requests and high concurrency in my course projects, the sluggish responses would make me question everything.

The page development tutorial for the Cangjie Language Mall application is coming to an end. Today, we are going to share the Settings page: The navigation bar is still in the old style. I have introduced it many times before, so I won't repeat it today. The content of this page mainly introduces the usage of the List container. It can be seen that the list content is divided into three groups, so we need to use ListItemGroup. However, the first group has no title, so we can directly use ListItem. The layout is very simple. The specific code is as follows: ListItem{ The following two groups of content both have titles. For the implementation plan, I suggest using the head of the List container. The method is to first define the header component and then reference it in the ListItemGroup. The specific code is as follows: @builder func itemHead(text:String) { ListItemGroup(ListItemGroupParams(header:{=>bind(this.itemHead,this)('账号设置')})){ The remaining content is the content part of the following two groups. It can be seen that they are almost the same. Therefore, we can customize components to save code. Let's introduce the relevant content of custom components again. First, create a new file, define the style and the required parameters. Taking the content of this article as an example, the specific code is as follows: @Component @prop var title:String @prop var icon:CJResource @prop var subTitle : String } } ListItem{ Finally, the content in the group has a divider. Both List and ListItemGroup provide the divider attribute divider. Here, we only need to use ListItemGroup. It should be noted that the width of the divider should not be set to a value less than 1, otherwise some parts may not be displayed. .divider(strokeWidth: 1.vp, color: Color(216, 216, 216), startMargin: 10.vp, endMargin: 0.vp) That's all for today's content.

Directly implement your eBike specific parameters in zip container is easy. Solution: File include/eeprom.h contains default parameters, like assist factor, torque sensor calibration and so on. Open configuration setting of your eBike, select "Display" section and choose "yes" on "Reset def". Existing configuration long pressing power button and power off. Green LED on nRF-dongle appears and finished. 2. Longer motor initialization time in lower temperature environment Problem: Display is locked at boot screen for 3-5 min in winter time. Lower temperature is longer locked time. It seems depends on temperature atmosphere, obviously observed in lower than 10degC environment. Once display transits main screen, everything works perfectly. Solution: I strongly want to solve this issue. This is why I made up build environment even binary is provided. 3. Assist level unintentionally changed Problem: Assist level is suddenly changed during riding without any +/- button operation. Solution: Add 0.1uF(104) capacitor between 2 wire of each Up/Down button. This issue seems due to electrical noise. (end of article)  ( 3 min )

By: Alireza Minagar, MD, MBA, MS (Bioinformatics) Software Engineer We’ve long treated artificial intelligence as a tool—one that mimics human behavior, solves problems, and automates tasks. But the deeper I dive into both neuroscience and software engineering, the clearer it becomes: AI is not just inspired by the brain. It’s becoming a second form of cognition. 🧠 Biological Cognition: Chaotic Brilliance We: Infer from incomplete data Feel our way into decisions Dream in abstractions we don’t fully understand This isn’t randomness—it’s organic computation. 🤖 Machine Cognition: Elegant Precision Deterministic Structured Scalable It doesn’t “think” the way we do—but it processes vast information in milliseconds, uncovers hidden patterns, and outputs results we sometimes don’t understand.

But here’s the truth: You weren’t lazy. exhausted from solving everything alone. Here’s the kicker: even the most basic code functions don’t run in isolation. Think about .map(). [1, 2, 3].map(num => num * 2) // → [2, 4, 6] It asks for help — from a function you give it. delegating. That’s how most of code works: Frameworks abstract the hard stuff Helpers reduce repetition Collaboration makes ideas real faster So… why do we expect ourselves to work alone 24/7? Being a dev often means: Wearing multiple hats (frontend/backend/devops/docs/client support…) Learning while building Debugging alone at 2:43 AM Saying “I got it” when you don’t This “solo hero” mindset creates guilt when we stop — Because if we confuse burnout for personal failure, break. Actually Looks Like Asking for help doesn’t mean you’re incapable. like a dev — efficiently. ✅ You ask a teammate to pair-program for 20 minutes useEffect with a custom hook someone already made These aren’t weaknesses. They’re strategies. It’s not cheating. If your brain is foggy, if your body’s done, You’ve just reached a limit — and limits are data. So pause.

The Use Case At first, we had a simple schema: session_id (PK) approval_id (PK) Each Approval was linked directly to a WorkSession. But soon, a real-world need surfaced: Sometimes, one approval covers multiple sessions. But our database design didn't allow that. Instead, we had to duplicate approval records for each session — not ideal. The Solution session_id (FK) Now, a single Approval can be reused across multiple sessions. In the UI, we added a feature for users to search and select existing approvals, reducing redundancy and simplifying workflows. Why It Matters Easier to maintain & more accurate Reflects actual business logic These kinds of small design shifts from tightly coupled to normalized lead to systems that scale better, adapt to real-world use cases, and are easier to evolve.  ( 3 min )

Before we begin, note that there are two ways to deploy an Astro site on Railway: If your website uses SSR (Server-Side Rendering) or adapters. If your website is completely static. This post focuses on the second option: deploying a fully static Astro site on Railway. First, create your Astro project. Open your terminal and run: npm create astro@latest Follow the prompts to set up a static site. In my case, I'm building a personal portfolio to showcase my projects. You can fork or contribute to my repo here: https://github.com/Gersomsim/Pesonal-web Once your site is ready, modify your package.json: "scripts": { "dev": "astro dev", "build": "astro build", "preview": "astro preview", "start": "npx serve dist" // Crucial for static Astro sites } Then add this at the end of package.json: "engines": { "node": ">=18.0.0" // Tells Railway the minimum Node.js version } Projects scaffolded with Astro default to static output. Just confirm: import { defineConfig } from 'astro/config'; export default defineConfig({ // output: "static" (default value) }); Uncomment the output line if unsure, but it’s static by default. Add this to instruct Railway’s builder: { "builds": [ { "src": "package.json", "use": "@railway/nixpacks" } ] } Create this file to configure static file serving: { "root": "dist", "clean_urls": true, "routes": { "**": "index.html" } } With these steps complete, your static site is prepped for Railway. Deployment is straightforward: 1.- Log into Railway with your GitHub account You might wonder: "Why Railway over Vercel/Netlify?" While alternatives exist, I chose Railway for its $5/month Hobby Plan. This lets me host: Frontend projects Backend APIs (Laravel, NestJS, etc.) My entire portfolio For the price of a coffee, I avoid juggling multiple services.

As a third-year computer science student, I often found myself grappling with the sluggishness of web applications. While textbooks painted pictures of efficiency, the reality of complex, real-world projects frequently led to frustration. My perspective on "efficiency" and "elegance" in web development shifted dramatically after I stumbled upon a particular open-source project. Initially, my expectations were modest. The market is saturated with frameworks, and for a new contender to make a mark, it needs to offer something truly exceptional. However, as I delved into its design documents—which were notably concise and focused—and experimented with its sample projects, which launched swiftly and consumed minimal resources, a gut feeling told me this could be the solution I'd been searching…  ( 6 min )

The Problem We Aimed to Solve… Traditional Jira burndown charts, while useful, often fall short in providing the insights that project managers and teams need to make informed decisions. We repeatedly encountered several challenges: Scope Changes: Standard burndowns don’t effectively track or visualize how project scope changes over time Resource Planning: Traditional charts fail to account for varying team capacity and velocity. They also fail to explain how your resource model assumptions are playing out with your real project data. Multiple Perspectives: Teams needed to track different subsets of work (like features vs bugs) within the same project.

June 14 2025 I gave my Hack Vega exam, and it went decently well. It wasn't too overwhelming, and I think I managed to answer most questions confidently. The exam had a mix of everything – logical reasoning, english and quant. Let’s hope it turns out well! I didn’t want to completely burn out, so I did a light DSA brush-up — nothing too intense, just revised some commonly used patterns and solved a few quick problems to keep the rhythm going. Even a little practice every day adds up. Later in the evening, I got curious and ended up reading about two system design topics randomly via ChatGPT. It’s fascinating how deep and layered system design can get. From scalable chat systems to caching mechanisms, there’s always something new to uncover. I wasn’t planning to dive into it today.

Today was all about revisiting Step 5: Copywriting and it took more energy than expected. Copywriting Foundations I Revisited John Caples – The Copywriting: Tested Advertising Methods Joseph Sugarman – Triggers Together, these gave me a strong foundation for simplifying and clarifying the page copy. What I Changed Because of my growing affection for the project (as I mentioned in my last post), I had included too much detail, especially in the “Customer Testimonials” section. Here's what I did: Printed and categorized all review data Sorted by sentiment and theme to avoid bias Identified overlaps and cut redundancy Trimmed long sentences and replaced them with impactful phrases Removed weaker local testimonials (even the ones I liked), especially those that only worked because of local dialect. It hurt a little, but it helped the copy. Writing on paper helped me spot small contradictions in my draft and source materials, which explained why I’d been confused several times before. It was a relief to finally resolve them.

Overview certwatch-js is a lightweight Node.js library designed to monitor the validity and configuration of SSL/TLS certificates used by web services, APIs, and infrastructure endpoints. It programmatically retrieves certificate metadata such as issuer, subject, validity period, and expiration date by establishing a secure connection to the target host. This information is then evaluated to determine whether the certificate is close to expiration or misconfigured. By integrating certwatch-js into DevOps pipelines, you can proactively detect issues like upcoming certificate expiry, self-signed or untrusted certs, and misaligned subject details. This helps prevent production outages, security incidents, or compliance violations due to overlooked certificate renewals. The tool is ideal for…  ( 4 min )

In a recent project, we ran into an interesting design limitation involving a status tracking system where multiple entities were tied to a single parent event. Each entity could become active or inactive at different times, but the system was recording status changes at the parent level, not individually. This led to a common but critical problem: updating the status for one entity ended up updating it for all related entities, even if some were still active. While this might be fine in tightly coupled scenarios, it didn’t reflect the real-world behavior of our system. The Problem The Solution A simple shift in data design made the system far more flexible and accurate.  ( 3 min )

Managing multiple asynchronous operations in JavaScript can become complex. Fortunately, JavaScript provides several built-in methods—.all(), .allSettled(), .race(), and .any()—to handle such operations gracefully. This blog provides a professional, structured comparison of these promise methods with real code examples and practical use cases. Understanding the Basics Promise.all() – Wait for All to Succeed Use Case Example const p1 = Promise.resolve('Result 1'); const p2 = Promise.resolve('Result 2'); const p3 = Promise.reject('Error in p3'); Promise.all([p1, p2, p3]) .then(results => console.log('All success:', results)) .catch(error => console.error('At least one failed:', error)); Output At least one failed: Error in p3 Promise.allSettled() – Wait for All to Finish (Regardless of Success or Failure) Use Case Promise.allSettled([p1, p2, p3]) .then(results => console.log('All settled:', results)); Output [ { status: 'fulfilled', value: 'Result 1' }, Promise.race() – First Settled Wins Use Case Example const fast = new Promise(resolve => setTimeout(() => resolve("Fast!"), 100)); const slow = new Promise(resolve => setTimeout(() => resolve("Slow!"), 500)); Promise.race([fast, slow]) .then(result => console.log('Winner:', result)); Output Winner: Fast! Promise.any() – First Successful Only Use Case Example const fail1 = Promise.reject("Fail 1"); const fail2 = Promise.reject("Fail 2"); const success = Promise.resolve("Success!"); Promise.any([fail1, fail2, success]) .then(result => console.log("First success:", result)) .catch(err => console.log("All failed", err)); Output First success: Success! Summary Use Promise.all() when everything must succeed. Use Promise.allSettled() to inspect all outcomes. Use Promise.race() for the fastest result (good or bad). Use Promise.any() to get the first successful result only.  ( 4 min )

SwiftUI has revolutionized iOS development with its declarative approach, but performance optimization remains a critical concern for creating smooth, responsive apps. With the introduction of Instruments 26, Apple has provided developers with powerful new tools to identify and resolve SwiftUI performance bottlenecks. Performance problems in SwiftUI apps typically manifest as hitches, hangs, or delayed animations. These issues often stem from two primary causes: Long View Body Updates: When view body computations take too long, they can cause the app to miss frame deadlines, resulting in visible hitches during animations and scrolling. Unnecessary View Updates: Even fast view updates can accumulate and cause performance problems when too many views update unnecessarily in a single frame. …  ( 5 min )

If you’ve ever stared at a wall of escaped backslashes and quotes and thought “what am I even looking at?”, you’re not alone. JSON escaping and unescaping can be confusing — but once you understand the why and how, it becomes a powerful tool in your dev toolkit. JSON Escaping is the process of converting special characters in a string into their escaped equivalents so they can be safely included in JSON format. This ensures that characters like quotes, backslashes, and control characters don't break the JSON structure. JSON Unescaping is the reverse process - converting escaped characters back to their original form to make the string human-readable or usable in your application. Here are the most frequently escaped characters in JSON: " becomes \" \ becomes \\ / becomes \/ (optional b…  ( 5 min )

Day 1: First Encounter with Hyperlane I came across the Hyperlane Rust HTTP framework while browsing GitHub, and its advertised performance metrics immediately piqued my interest.

A high-throughput Kafka consumer doing too much can end up hogging shared resources like the database or Elasticsearch—especially if it’s living alongside critical services in the same pods or nodes. This post walks through a pattern that helps decouple processing, apply back-pressure, and keep systems healthy. In a typical setup: A REST service triggers events. A Kafka producer sends those events to a topic. A Kafka consumer picks up the messages and immediately does all the work—like calling DB, making API calls, indexing in Elasticsearch, logging, etc. This works… until it doesn’t. Under load, the consumer overwhelms the s…  ( 5 min )

The official docs for startTransition bring a problematic example, which is also mentioned in FAQ. But why doesn't the React team add an AbortSignal to the transition function? That way we can just check the cancellation status to avoid the dirty rendering. I understand it might be useless once the AsyncContext has been delivered. But before that, it makes the official example work correctly, right?  ( 3 min )

As a computer science student nearing my senior year, I've been fascinated by the progression of software architecture.

Choosing a suitable framework to navigate this microservices environment has been a key focus of my recent explorations. Fortu…  ( 9 min )

While building an application or authentication system, it's crucial to ensure that users have access only to the data they are authorized to view, and each access must be granted to verified users only. Unauthorized access to your data can raise concerns about your application's workflow and authenticity. OAuth 2.0 and OpenID Connect are two protocols that introduce security measures and token-based authentication for applications, adding a security layer to your application. These measures help make accessing your application data a secure and authentic process. The tokens used for this process are Access Tokens and Refresh Tokens. An access token is a short-lived token used to access data in your application. Whenever a user requests data, this token is verified for accessing the data.…  ( 5 min )

As a third-year computer science student, I often found myself grappling with the sluggishness of web applications. While textbooks painted pictures of efficiency, the reality of complex, real-world projects frequently led to frustration.

As a computer science junior, my work on a web service project introduced me to the Hyperlane framework. This high-performance Rust HTTP framework fundamentally altered my view of web development. Here's a genuine account of my experience learning and using Hyperlane. ctx Abstraction When I first began using Hyperlane, I was immediately impressed by its clean Context (ctx) abstraction. In other frameworks, I was accustomed to writing more verbose calls, such as: let method = ctx.get_request().await.get_method(); With Hyperlane, this simplifies to a single line: let method = ctx.get_request_method().await; This design significantly boosts code readability, especially when handling complex business logic, by removing the need for deeply nested method calls.

When learning the idea behind MCP Servers, I kept running into the same wall: tools that demo well but take hours to adapt and most focus on integrating with Claude Desktop directly, and not into a web stack... in local or deployed environments. So I built MCP Burst — not to compete with what’s out there, but to fill the gap I couldn’t find a fix for. Disclaimer: This post was written and formatted by my custom GPT, doing it's best to sound just like me! There are many impressive repos out there that make great use of MCP Servers, but watching others on YouTube implement them, I quickly realized that what I needed was a framework I could understand and so I built it utilizing the official SDK. MCP Burst is a minimal but complete(?) setup that you can run as-is or drop directly into any Nod…  ( 4 min )

Goroutines are one of the most powerful features in Go. With just one keyword go, you can execute functions concurrently and build highly scalable systems. But power comes with responsibility. In real world projects, careless use of goroutines can lead to memory leaks, deadlocks, race conditions, and unpredictable behavior. In this post, we’ll explore common goroutine pitfalls and how to avoid them with practical examples you can apply in production. A goroutine starts and never exits, typically because it's waiting forever on a channel or a blocking operation. func process(ch chan int) { for val := range ch { fmt.Println(val) } } func main() { ch := make(chan int) go process(ch) // forgot to close the channel } The process() goroutine never exits, leading to …  ( 5 min )

After much dedication and a significant learning curve, I'm delighted to share my interactive online resume! This project is particularly special to me because it's one of the very first project I built from the ground up while diving deep into the React. Key Features: Smooth Full-Page Snap Scroll ➡️ One of the core UX features is the snap-scroll navigation. This creates a polished, controlled scrolling experience where each section neatly snaps into view. How it works: Achieved primarily using CSS scroll-snap-type: y mandatory; on the main container and scroll-snap-align: start; on each section. This ensures that when a user scrolls, the viewport "snaps" to the beginning of a new section. I also implemented conditional snapping with Tailwind's responsive prefixes (sm:snap-none md:snap-y md:snap-mandatory) to ensure a smoother, more natural scrolling experience on mobile devices where content might extend beyond min-h-screen. Responsive Project Showcase 💻 My projects are displayed in a clean, responsive grid, making it easy to browse on any device. Check it Out! 👉 Live Demo: https://react-basic-resume.vercel.app/ The complete source code is also available on GitHub.

Enhance Your Retrieval Accuracy with Bedrock Knowledge Base Metadata In one of the projects where I worked with Retrieval-Augmented Generation (RAG) using AWS Bedrock and Knowledge Base, I encountered a retrieval accuracy issue. The client had multiple documents containing similar content, but each was tailored for different audiences. Imagine a high school textbook and a college textbook. Both may cover the same subject matter, but typically, the college version contains more advanced content. Now, how can we ensure that high school students only retrieve information from the high school materials, even when both files contain overlapping topics? The solution I implemented for this challenge was to use metadata filters. Metadata filters allow you to classify your files in a way that Bedro…  ( 4 min )
